The implementations involve obtaining a virtual model of the bone, a resection volume defined relative to the virtual model of the bone, and a reference guide defined with respect to the resection volume. Section planes are successively arranged along the reference guide, and each section plane intersects the reference guide and intersects the resection volume.

The milling path is then generated by combining the section paths and the transition segments.

The controller utilizes the second stereoscopic sensing system to sense light from the object and track the object according to a second resolution that is lower than the first resolution. The controller obtains data related to the object from the second stereoscopic sensing system and modifies control of the sensing elements of the first stereoscopic sensing system based on the obtained data related to the object.

Abstract: Robotic surgical systems and methods for controlling movement of a surgical tool involve a manipulator, a force/torque sensor to measure forces and torques applied to the surgical tool, and a control system. The control system obtains a virtual boundary for the tool that is a three-dimensional and elongated virtual tube to predefine a tool path for the tool. The control system defines virtual constraints to constrain movement of the surgical tool to be along the tool path defined by the virtual tube. An input is received from the force/torque sensor in response to user forces and torques manually applied to the tool by a user. The control system simulates dynamics of the tool in a virtual simulation based on the virtual constraints and the input from the force/torque sensor and commands the manipulator to advance the tool along the tool path based on the virtual simulation.
